Construction of Mansfield Dam, originally Marshall Ford Dam, began as a joint LCRA/Bureau of Reclamation project.
Monthly generation is reported through EIA-923. Capacity factor uses the current EIA nameplate capacity and is shown only for complete calendar years.
Observed ERCOT settlement prices at HV_BESS1_RN over 365 days (2025-09-18 to 2026-09-17). This plant is also crosswalked to MAR_MARSFOG1, MAR_MARSFOG2, MAR_MARSFOG3; the point with the deepest price history is shown.
The TB2 figure is a price benchmark, not revenue: it values one perfect-foresight cycle per day between the 2 cheapest and 2 dearest hours of each day, gross of round-trip losses, and excludes ancillary services and any physical dispatch constraint. It describes what this node’s price shape was worth over the window — it is not this asset’s realized capture, and no dispatch is assumed or modelled.
